This book provides a very practical way to resolve crises in relationships and turn them into opportunities for win-win cooperation. The ideas in the book are very enlightening, like the "secrets of effectively resolving 'critical conflicts'" mentioned in the book, which gave me a new understanding of how to deal with conflicts in life and work. And the descriptions in the book are very vivid. For example, solving a key conflict is likened to solving the mystery of the double helix structure of DNA, which is very vivid. I think this book is not only suitable for married men, but also for anyone who wants to improve their relationships.
